Uneven Heating – One Side Hotter Than the Other
2026-08-06 12:29
| Step | Operation | Criterion |
|---|---|---|
| Step 1: Multi-Point Temperature Check | Use infrared thermometer to measure left, center, right, top, and bottom of heating plate | Temperature difference exceeds 10℃ → heating plate issue |
| Step 2: Check Voltage | Measure socket voltage with multimeter | Below 200V or above 240V → unstable voltage, install voltage stabilizer |
| Step 3: Inspect Heating Plate Surface | Visually check if plate is flat with no obvious warping | Visible bending → heating plate is warped and needs replacement |
| Step 4: Check Installation | Inspect screws where heating plate connects to machine | Loose → tighten and re-measure temperatures |
One-Sentence Summary: A temperature difference over 10℃ is a machine issue, not operator error – time to call after-sales support.
Prevention: Upon first use of a new machine, measure all five points with a thermometer and record the data. Re-measure monthly to catch issues early.
